Abstract
The utility model relates to tightening structures, in particular to a tightening structure of a numerical control knife rest, and belongs to the technical field of vertical lathe equipment. The tightening structure of the numerical control knife rest comprises a rotary sliding seat, and a pressing plate is fixed on the rotary sliding seat through a taper pin and a connecting bolt on the two sides of the pressing plate. The center position of the pressing plate can tightly press a copper outer hexagon bolt of a ram through threaded connection. The tightening structure of the numerical control knife rest is simple, compact and reasonable in structure, the copper outer hexagon bolt is mounted on the pressing plate and abuts against the ram to enable the ram not to slide down due to self weight, after the numerical control knife rest is mounted on a machine tool, a brake servo motor is then mounted, sliding of the ram is avoided, and the servo motor is effectively protected.
Description
Technical field
The utility model relates to a kind of tightening structure, and a kind of tightening structure of numerically-controlled slide specifically belongs to vertical vehicle device technical field.
Background technology
In vertical garage industry, the ball screw of numerically-controlled slide transmission does not have auto-lock function, in the time that numerically-controlled slide is installed to lathe, must band-type brake servomotor be installed, and prevents that ram from gliding because of deadweight, but easily band-type brake servomotor is collided with bad in the time that handling is installed.In view of the problem of above-mentioned existence, in the urgent need to developing a kind of tightening structure of new numerically-controlled slide.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of tightening structure of simple in structure, ingenious, rational numerically-controlled slide is provided, and avoids ram landing, has effectively protected servomotor.
The technical scheme providing according to the utility model, a kind of tightening structure of numerically-controlled slide comprises rotary slide base, rotary slide base front end face is provided with open slot, ram is slidably connected in open slot, open slot place is provided with the pressing plate that ram is pushed down, and it is characterized in that: pressing plate is fixed on rotary slide base by taper pin and the connecting bolt of both sides.Described pressing plate center is threaded connection the copper outer-hexagonal bolt that can compress ram.
Further, open slot vertically arranges.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, copper outer-hexagonal bolt is arranged on pressing plate, and withstands ram; do not allow it glide because of deadweight, after numerically-controlled slide is installed lathe, then band-type brake servomotor is installed; avoid ram landing, effectively protected servomotor.
Accompanying drawing explanation
Fig. 1 is the utility model front view.
Fig. 2 is the utility model top view.
Description of reference numerals: 1-ram, 2-rotary slide base, 3-pressing plate, 4-taper pin, 5-connecting bolt, 6-copper outer-hexagonal bolt.
The specific embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1 and 2, the utility model mainly comprises rotary slide base 2, and rotary slide base 2 front end faces are provided with open slot, and open slot vertically arranges.
The ram 1 that is slidably connected in open slot, open slot place is provided with the pressing plate 3 that ram 1 is pushed down, and pressing plate 3 prevents that ram 1 from skidding off open slot.Described pressing plate 3 is fixed on rotary slide base 2 by taper pin 4 and the connecting bolt 5 of both sides.
Described pressing plate 3 centers are threaded connection the copper outer-hexagonal bolt 6 that can compress ram 1; when moving linearly ram 1 up and down, copper outer-hexagonal bolt 6 need to use very large power; frictional force has exceeded the gravity of ram 1, has avoided ram landing, has effectively protected servomotor.
The utility model compared with prior art; be a little: the ball screw of numerically-controlled slide transmission does not have auto-lock function; in the time that numerically-controlled slide is installed lathe; must band-type brake servomotor be installed; prevent ram deadweight downslide; but easily band-type brake servomotor is collided with bad in the time that handling is installed; copper outer-hexagonal bolt is arranged on pressing plate; and withstand ram; do not allow it glide because of deadweight, after numerically-controlled slide is installed lathe, then band-type brake servomotor is installed; avoid ram landing, effectively protected servomotor.
Claims (2)
1. the tightening structure of a numerically-controlled slide, comprise rotary slide base (2), rotary slide base (2) front end face is provided with open slot, ram (1) is slidably connected in open slot, open slot place is provided with the pressing plate (3) that ram (1) is pushed down, and it is characterized in that: pressing plate (3) is fixed on rotary slide base (2) by taper pin (4) and the connecting bolt (5) of both sides; Described pressing plate (3) center is threaded connection the copper outer-hexagonal bolt (6) that can compress ram (1).
